S-Spheres®

Strongest hollow microspheres in size 100-300 micron

Hollow microspheres

Usually, strength and lightness are two properties that are tough to combine in one single product – though necessary in many industries nowadays. We are now capable of combining these two important characteristics in a single product S-Spheres: it is lightweight and has high strength. Furthermore, our new product is affordable and has at the same time the outstanding quality. The following features are paramount for its success:

Perfect spherical shape

White color

Outstanding strength

Lightness

Gas and water resistance

Water insoluble and chemicals resistant

High melting point (above 1200 C°)
